Let F(x) = x^2 + 2x -8
Adding 1 and - 1 at equation
F(x) = x^2 + 2x + 1 - 1 -8
Rewrinting the first 1 = 1^2
F(x) = x^2 + 2x + 1^2 - 1 - 8
Now look:
x^2 + 2x + 1^2 = ( x + 1)^2
Then,
F(x) = (x + 1)^2 -1 -8
F(x) = (x + 1)^2 -9
This is the answer !
If us to want.
(x + 1)^2 -9 = ( x+1)^2 - 3^2
= ( x+ 1 -3).(x +1 +3)
= ( x - 2).(x +4)
Answer:
there are 3 ways that it can be 10:
6,4
5,5
4,6
Answer:
The answer is A
Step-by-step explanation:
That is because one million has 6 digits and I'm guessing that the flea is measured in millimeters. So you just add the two decimal places. So, you add the one million (count the number of zeroes in a million) to the number of decimal places that the dot was moved. So from a measure of meter you move the dot one place right and you decrease the measuring unit. So, first is meter then centimeter and then millimeter.
Answer:
12
Step-by-step explanation: it is 12 because LCM is least common mulitiple. The LCM is the smallest number of all the number that can DIVIDE EVENLY. 6 cannot divide evenly.
The coordinates of Point A are (-13,-13)
Step-by-step explanation:
The formula for mid-point of two points (x1,y1) and (x2y2) is given by:
Given
M = (-5,-9)
B(x2,y2) = (3,-5)
Putting the values
Comparing respective elements
Hence,
The coordinates of Point A are (-13,-13)
